发帖数: 837 | 2 The answer to your question is a definite no.
Roughly speaking, weeds could be grassy or broadleaf, summer annual or
winter annual or perennial (let's just ignore biennials for simplicity
purpose). So there is 6 combinations.
Winter annuals generally germinate in the fall, green through the winter,
set seeds in the spring and die in the summer. A recent post showed
pictures of bittercress and shepherd's purse, which are both broadleaf
winter annuals:

发帖数: 837 | 3 If you decide to use chemicals, two types will kill many broadleaf weeds
including Broadleaf Plantain:
1. Glyphosate. This is the single active ingredient in Roundup. Don't
worry about the different names/brands. Get a product with high
concentration of glyphosate. They all have similar effectiveness. Note
this one is non-selective in that it kills almost all grasses, including
good ones.

发帖数: 837 | 5 First of all, the best defenses against weeds are a healthy and thick lawn,
mowing high, and watering as infrequently as grass allows and as deeply as
soil allows.
Personally, I think weed & feed products for post-emergent weed control is a
great marketing gimmick for the unassuming consumers. It is banned in
Canada for a reason. Why? Broadleaf herbicides are best when applied to
the leaves, so imagine how effective could a granular form be. It could
still be effective, but compared to liqui... 阅读全帖 |

发帖数: 328 | 13 I think most of the broadleaf weed killers work similarly ba. such as Bayers
, Spectracide, weed b gone. Be sure to check the bottle, it usually states
something like "kill the weeds not the lawn". If you are in the south, be
careful, certain warm season grass types (such as St. Augustine grass) can
be sensitive to weed killers.
I don't usually mind digging out dandelions myself. With a fishtail weeder
and do it after some rain, it takes little effort. |

发帖数: 4125 | 14 Wild rabbits are vegetarians. Their diet is 90% grass. They will eat
almost any type of vegetable in the summer.
Grasses, broadleaf weeds, garden crops, beans, peas, cabbage and lettuce are
all foods of choice.
In the winter wild rabbits will eat tree buds, twigs and bark.
A female rabbit can produce three or four litters a year, with four to six
young in each litter. Over a period of five years, a single pair of rabbits
and their kin would number around 350,000, this is no joke.

发帖数: 837 | 15 Indeed, pulling is the best if you can manage it and are willing to commit
the time.
Other than that, there are chemical solutions that kill weeds but not
grasses. For example, 2,4-D can be used for dandelions and plantains;
adding Dicamba and MCPP kills a wider range of broadleaf weeds; and
Triclopyr can be used for a few tougher ones. (Note what I mentioned here
are active ingredients, not brand/product names.) For these types of
chemicals, just spray the area where you want to control weed... 阅读全帖 |

Glyphosate (N-(phosphonomethyl)glycine) is a broad-spectrum systemic
herbicide used to kill weeds, especially annual broadleaf weeds and grasses
known to compete with commercial crops grown around the globe. It was
discovered to be a herbicide by Monsanto chemist John E. Franz in 1970
看一下，除草剂是1970年出来的，转基因第一个作物是1995年 |

post-emergence herbicide一般在5-6月使用，当中Bayer Advanced "All-in-One"

有机肥料当中milorganite是最容易买到和最受推崇的，但是不便宜（相对于氮肥的含

土壤好才是真的好，所以增加有机物含量以及对微生物环境还有有益的worms，细菌啊

WBG works slowly into the root, so check back in 2 week. However, it is
effective to broadleaf weeds, but not that much to grassy weeds, so you need
to know what your weeds are.
Moss killers most likely have ferrous/iron sulfate as the active ingredient.
Ferrous/iron sulfate is also used medically to treat iron deficiency, so
it isn't in the same category as the toxic herbicides like 2,4-D, triclopyr
or glyphosate.

In the larval stage, neither rootworm species is known to survive on
